terminal profile: numeric value fields (soft keys, channels, screen, ND/NK, frames), doc corrections (v2.2.21)

- TP_BITS: fill the value-field rows that were all-RFU (byte 11 soft keys,
  byte 13 b6-b8 channels, byte 14 height + ND/NK/sizing, byte 15 width +
  variable fonts, byte 16 effects + width reduction, byte 19 TIA version,
  byte 24 max frames), per TS 102 223 5.2.
- TP_VALUE_FIELDS + tpGetValue/tpSetValue (little-endian bit ranges) and
  number inputs in the Configure dialog; the byte 11 'FF' reserved note
  stays visible in the hint; flags remain checkboxes.
- Tests: new label spot checks, value round-trips/clamping, render guard.
- docs/TERMINAL_PROFILE.md: byte 22 b1 not universal (S25 Ultra/edge 60
  clear, WISMO228 sets), b2/b3 counts fixed, byte 21 markup present in
  Pixel 3/4 + OnePlus 12, ESN is a capability bit not a CDMA marker,
  0xFE sentinel unexplained by the spec, channel count 5 added, new
  Appendix A with the value-field ranges.
- Version 2.2.21, SW cache otaman-v188.
